Step-by-step explanation:
2 (yellow) / 3.5 (blue)
that means, out of 2+3.5 = 5.5 units 2 are yellow, and 3.5 units are blue.
now in a 3 / 4.5 ratio we have 3+4.5 = 7.5 units, where 3 units are yellow and 4.5 units are blue.
let's bring both ratios to the same denominator (bottom part of the fraction).
if we multiply 3.5 by 2 we get 7. and multiplying 4.5 by 2 gives us 9.
and the smallest common multiple of 7 and 9 is 63.
so, let's bring both fraction to .../63.
3.5 × 2 × 9 = 63
so, the ratio is
2×2×9/63 = 36/63
and
4.5 × 2 × 7 = 63
so, that ratio is then
3 × 2 × 7 / 63 = 42/63
now we can see clearly that the first ratio
2/3.5 = 36/63 has fewer units of yellow in the mix than the second ratio
3/4.5 = 42/63.
so, the second mixture is more yellow.
Answer:
x = -75
Step-by-step explanation:
x = - 45 ( multiply both sides by 5 to clear the fraction )
3x = - 225 ( divide both sides by 3 )
x = - 75
Answer: x = -12 is the correct answer
Step-by-step explanation: the moderator that deleted this if is so wrong then just tell me why is wrong if you are so smart.
#1) The correct answer is A) 5.
#2) The correct answer is C) the number of cans collected per day.
We find the rate of change by finding the change int he outputs, the change in the inputs, and writing it as output/input:
(20-15)/(2-1) = 5/1 = 5
The rate of change tells us how many cans (on average) per day were collected.
